The crankshaft seal is a critical component in vehicle engines, ensuring the prevention of oil leaks and maintaining the integrity of the crankshaft. The Crankshaft Seal 038103171 is a high-performance solution designed for Audi vehicles, offering durability and precision. This article delves into the product's features, advantages, technical specifications, applications, and the company behind it, JULU YJM HWMF SEAL CO.,LTD.
The front crankshaft seal and rear crankshaft seal are essential for maintaining engine efficiency. The crankshaft seal (OEM number: 038103171) is engineered with a left-hand twist swirl design, specifically tailored for Audi models. This design ensures a secure fit and optimal performance under demanding conditions. The seal is constructed from high-quality PTFE (polytetrafluoroethylene) and ACM (polyacrylate rubber) materials, known for their resistance to high temperatures and chemical degradation.

One of the key features of this seal is the inclusion of a housing and mounting sleeve, which simplifies the installation process. It is crucial to note that the seal should be mounted dry, without the use of additional oil or grease, to ensure maximum effectiveness. This design not only enhances durability but also reduces the risk of leaks, making it a reliable choice for automotive applications.
| Parameter | Details |
|---|---|
| Material | PTFE and ACM |
| Design | Left-hand twist swirl |
